Topology and Nematic Ordering I: A Gauge Theory
Paul E. Lammert, Daniel S. Rokhsar, John Toner
We consider the weakly first order phase transition between the isotropic and ordered phases of nematics in terms of the behavior of topological line defects. Analytical and Monte…

Topology and Nematic Ordering II: Observable Critical Behavior
John Toner, Paul E. Lammert, Daniel S. Rokhsar
This paper is the second in a pair treating a new lattice model for nematic media. In addition to the familiar isotropic (I) and nematically ordered (N) phases, the phase diagram e…
